Application filed July 22,

his invention relates to improvements in sa wmills, and more particularly to the system or means for operating the log turners and niggers.

5 One of the objects of the present invention is to provide an improved system of the character referred to wherein a single control lever is provided for operating both the log turners and niggiers, and wherein means are l provided for selectively connect-ing the control lever to the latter.

Another object is to provide an improved svsteni of the character referred to wherein ai single control lever is provided for both the loe: turners and ni and which has all the advantages, as regfards ease and rapidity1 of operation, of such systems constructec` heretofore wherein separate control levers are used for the log turners and niggers.

Other objects and advantages will herein after appear.

For the purpose of illustrating' the invention, one embodiment thereof shown in the drawings, in which C Figure 1 is a diagrammatic plan view of the improv d system, partly Vin section, some of the parts beingr removed for the sake of cleainess;

Figi'. 6 is an end elevational view, looking toward the left in Figs. fland 5; and

Fig'. '7 is a sectional view, taken on the line 7-7 in Fig.

ln Fissi/'1, 3 and Ll are shown, in a, Lgeneral wav. the usual cvlinders l() and 1l for the nip;- ters. and the ldgf turner which includes the push arm ('vlinder 1L). and the hook arm cylinder lll, cylinder 1:. beinggj provided with an operating valve lfl enclosed in a valve chest and cylinder 13 being provided with a similar operating; valve enclosed in a valve ela-rt it?. 'lhe operating valves for cylinders and ll are of well known construction and operate to a mit fluid unde pressure toeither side of the pistons working; in these cylinders and to simultaneously provide an exhaust paws for the other sides of these pistons. A cylinders are also provided with 1926. Seia] N0. 124,188.

the usual operating valves to which are connected the stems 17 and 18, respectively, reciprocatory movement of the latter causing operation of the nigger valves to cause upward or downward movement of the pistons operating in cylinders 1() and 11. The construction just described is well known and has only been shown in sufficient detail to enable those skilled in the art to understand the manner in which the operating valves for the log turner and nigger cylinders are connected up in the improved operating system therefor.

rod 19 is supgriorted in suitable bearings 2t) and is provided at one end with an arm 21 fixed thereto and connected to the valve stem 22 for the operating valve of cylinder 123 through the rod 23 and the lever Q4 pivotally supported at 25. An operatingV arm 26 is fixed on the other end of rod 19 so that upon rotary movement of this arm in opposite directions about the axis of rod 19 the valve for cylinder 13 is operated to cause inward or outward movement of the piston working therein.

For thel purpose of moving the operating:y valve 14 for cylinder 12, a section of pipe 2T is loosely mounted on rod 19 between the bearing Q0 and the l'fearing at the right end of rod 19, and an arm 28 fixed to one end of this pipe section and connected to the stein 29 for valve 14 through the rod 29' and the lever 30 pivotally supported at 31, an operatingy arm 32 being fixed to the other end of this pipe section whereby arm 32 is operable upon rotary movement thereof in either direction about the common axis of rod 19 and pipe section 27 to effect movement of the operatingr valve 14 in either direction, the loose fit between rod 19 and pipe section 27 permitting of independent rotary movement of these parts by means of their respective operating arms 2G and whereby the operating' valves for cylinders 12 and 13 are independently operable.

The operating' valve for the nigger cylinder 1l is actuated in either direct ion by means of an arm 33 connected to the valve stein 18 and fixed on one end of a` seeond pipe section 34;- loosely fitted on rod 19 between the intermediate bearing 20 and the bearing at the lett end of the rod, an operating arm 35 hein;v fixed on the other end of the pipe section l The operating valve for the nigger cylinder 19 is actuated by an arm 36 connected to the valve stem 17 and fixed on a short red section 3T arranged in alignment with rod 19 and supported by suitable hearings 38, ein operating arm 39 being ixed, :is shown, on the right end of rod 3T.

Froni the foregoing it will be Seen that the operating arnis Q6 and for the log turner cylinders 12 and 13 and the operating` firing 35 :ind 39 :tor the nigger cylinders i() and il are supported for pivotal movement about :i common axis and are independenlj; nio 'aille vsih respect to ach other about thi-1 axis wherelqv the respective lie-:tons working in Rhei-1e 'jfiindewA muy he minded to iiioi'e in any desired direetion :ind independently of ezirh oihe AS more elim-ly sho n Fir' 5, ating .fir iis fill :and 32 for the leg turner :ire p ovided et heir respeitive emes with pins 4() :ind 4 ed therein :ind extending therethrough :vond e; Ph side thereof, while the operating :irins 35 :ind il?? lor the nigger (tylii'idiray err proiided zii their respective ends Willi wiiiiiler @im 4Q zuid 4f also fixed in these ends and ext-em i 1g tlierehnziiigli bevond opposite sides ot t ie saine. the pine being in the operi l alignment and parallel to rods 19 :ind 3T, and the respective ridjieent ends ot pins4 49 and 43 :ind thohe of pinsy 4l and 42 abutting for the purpose hereinafter expire ined.

messes to the common control lever 44 and the valve operating' mechanism for the log turner cylinders l2 and 13 simultaneously disconnected from lever 114i. The control lever lf-l mav now be moved in the same manner explained above in connection with the log` turner cylinders l2 and 13, whereby one or the other et operating' arms and 39 ma)y be rotate-1l hack and forth about the axis ot rod lt), or both of there arms simultaneously rotated for 'ard and hack vard, or one arm rotated forward and the other arm simultaneously rotated backward, this n'iovement of 'the opemtinff arms causing movement of one or the other ot the pistons in the nigger cylinders, simultaneous nl )ward or downward movement ot l-olh oi the-e pistons, or upward movement ot one piston and simultaneous down Yard movement of the other, thus providingy tor complete flexibility ot operation olthe nifl'fl'ers to handle the log; in any mauner desired.

This nier is tor simu]taneousl)7 moving the` shitt hars 4G and l9 laterall)Y hetween the pair ot operating' arms 32 and and the pair ot operating,r arms 2G and 39 to simultaneously connect and disconnect the logy turner cylinders 12 and 13 and the nigger cylinders l and l1 to and from the common control lever 44 therefor, will now he described, A har 56 is supported in suitable bearings 57 and for axial shifting movement, the end Vil ot this har heine' square and hearing 5S supporting the latter being provided with a square opening to loosely receive the same. as more clearly shown in Figi'. (i, wherehv bar 5G is held against rotar)v movement. A collar titl is tixed on liar 521i and provided with depending spaced lugs 6l loosely emhracingf shittiliar 4G to canse lateral movement thereo'l upon axial movement ot har 56 while permitting; of tree liaclqward and forward movement ot the shitt loar to under the action ot control lever -l-l. A similar collar (32 is til-ed on liar 5o and provided with deliending; spaced logs 3?, extending on either side oi shi'l't har t9 whcrehv the latter is also caused to move laterallyy upon axial movement ot har 56.

The arrangement ot collars and 62 and arms Gl and is such that upon shitting ot har 56 to its extreme position to the right, as viewed in Fig. E, shit't hars 4G and 49 will lie moved laterally into connecting engagement with the log turner operating arms 26 and 252 and the fixed arms 64 and 65 simultaizeously moved into locking engagement ot the pins 42 and 43, respectively, whereby the valve operatingr mechanism for the nigger cylinders l() and 1l is locked against moveni nt. A depending arm 66 is tixed on bar 56 adjacent the log turner operating arm and provided at its end with an opening;` ior receiving the outer end of pin 4l, a similar depending arm 67 heingy .tixed on loar 5o adjacent the other log turner operating arm 25S and being' provided at its end with an opening i'or receiving the outer end of pin 4P. Upon :hittingoi? har 56 to its extreme position to the left, the dependingT lugs Gl and (3?) will cause simultaneous lateral moveaient et shift hars 46 and 49 from pins 40 and ll to pins 42 and 43, respectively. This movement ot loar 56 will also cause movement ot arms (34. and G5 to the lett out ot' leckine engran'emait wili pins l2 and ll?? and si-l lel't into locking engagement with pins ll an l -l-). respectively. In this position of har 5t?, therefore, the valve operating mechanism for the nigger cylinders l0 and 11 is connected to the common control lever '-31.4 and the valve operating mechanism tor the logty turner cylinders 12 and 13 locked against movement.

member G8 provided with depending` lens of) straddline` har 5G is arranged loosely lietween collars 70 fixed on the latter and is pivof. all;7 connected at 71 to a suitable fixed hase 72. a weight l being tixed to the upper end ot memher 68 for the purpose hereina'tter explained. Memher G8 is connected through a rod 7l, a hell crank 75 pivotally supported at 7GA and a rod 77 to 'the depending arm 79 'l`-sliaped plate 79 pivotallv supported at titl. Rods 8l and 82 are pivotallv connected to plate 79. as more clearlyv shown in Fig. il. and extend upwardlyv through a plate 83 fixed to the floor. From the foregoing it will he seen that when the operator presses his foot n on the upper end ot rod Sl and moves the re downwardly, har 56 will he shifted axi- :f-v to its extreme position to the left, as vifvred in Figi: and that when the operator pnshcs down on the upper end ol.E rod 82 the s shifted axialljtv to its cxtreme porrii right. ll'hen har 56 is intermeditreme imsitions. the center of grav-- weight' Til is over the pivot point 7l so ,v the weight falls to either side ot this` yit point and acts to vieldinelvY hold har 5G one or the other of its extreme positions. lior the purpose of accommodatingr difieret operators. the controlling; movements ot i' explained aliove may he made to have,
